304 steel is a general-purpose stainless steel that is widely used to make equipment and parts that require good overall properties (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 16% chromium and more than 8% nickel. 304 stainless steel is a grade of stainless steel produced according to the American ASTM standard. 304 is equivalent to my country's 0Cr18Ni9 stainless steel.

304 stainless steel is a very common stainless steel. Its corrosion resistance is better than 430 stainless steel, corrosion resistance and high temperature resistance, and good processing performance, so it is widely used in industry and furniture decoration industry and food and medical industry, such as: some high-grade stainless steel tableware, bathroom kitchen utensils. Based on more than 20 years of manufacturing experience in industrial stainless steel welded pipe production lines, Hangao Tech (SEKO Machinery) has mastered the production process formula of 304 welded pipes with different diameters and different thicknesses, and has always led the direction of domestic industrial stainless steel welded pipe manufacturing machinery SS tube mill line in China. We have established a common material laboratory with domestic first-class stainless steel industrial welded pipe manufacturers to share experimental data, and are currently committed to continuously improving and innovating the process of stainless steel industrial welded pipe laser welding production lines to reduce costs.

304 stainless steel, as the most common steel in the market, has the advantage that it is a metal alloy. It is a food-grade steel that can be seen everywhere in our daily life, and has high safety and strong corrosion resistance. 304 stainless steel is in corrosion resistance. It is much higher than ordinary stainless steel in terms of formability and formability, so it is often used in some production lines with relatively high requirements, and is applied to important equipment and parts after final molding. And its own heat resistance is very good, which is a perfect match with the laser welding machine. During high-temperature laser welding, not only a flat weld can be formed, but also the entire stainless steel pipe will not be damaged. 304 stainless steel generally does not need to be plated on the surface, and it is perfect in itself.

Compatible with steel with better basic materials and completed by laser welding, it can perfectly show the characteristics of 304 stainless steel and increase the added value of the product.

At present, the laser welding process has become more and more mature, and the price is gradually decreasing, so now the market has fully accepted and begun to adopt the laser welding process on a large scale. But the quality of the equipment is mixed. Buyers need to adhere to the principle of "you get what you pay for" to make judgments. You can't just blindly pursue low prices to screen out manufacturers with superior cost performance.

Laser welding is more perfect than traditional welding technology in terms of appearance and final effect, especially for some industrial production projects that require beauty and safety, the use of laser welding can achieve very ideal results and automatic assembly line welding, It can also reduce the probability of defective products in the process of mass production. As an advanced equipment controlled by a digital computer, the reliability of laser welding equipment is beyond doubt.
